My opinion is that you could have already very good results just microdosing 1p-lsd.Sunifiram ,eventhough is quite good has a risk of forming cancerous cells,if I recall correctly.Noopept is good too,but I will try always to keep the complexity of stacking to a certain minimum since you could never predict the interaction of the compounds even if in theory could be safe.
I've only properly read up on microdosing among those, besides the nicotine, and I'd say as long as you don't intend to use them every day, it's fine. Microdosing works best really when it's spread out so the tolerance is nill, and nicotine is kind of shitty too and you don't want to go down that line if you aren't already a smoker IMO. Try to replace it with something else if possible
LSD is plenty stimulating as it is. But modafinil could have a tuning effect on your thought process and remove some of the excess information. Psychedelics open your perception while most stimulants narrow them (we give lab grade speed to kids with wandering minds)
I dosed 300mg adrafinil then another 100ish. Im a little over stimulated now but not bad. With a MD of lsd it might be too much.
Microdosing lsd is sub perceptive btw idk why ppl are saying itll necessarily negatively impact its known for being used for focus and neurogenesis.
